Problems solved by technology

[0002] At present, due to its good storage and portability, plastic packaging bags can quickly and efficiently store and transport products. They are more and more widely used in our daily production and life. Plastic films are now common daily necessities. Plastic film has the advantages of good transparency, good moisture resistance, excellent heat resistance, convenient use, and low price, and is widely used in various industries. At present, the plastic film on the market is mainly polyethylene plastic film, but some products There will be problems such as wrinkles, poor transparency, uneven thickness, and many fish eyes in the film bubble
Some plastic films are used for food packaging, but they contain toxic plasticizers, which affect the quality of food and endanger human health
[0003] At the same time, packaging bags are often used outdoors, and they are exposed to the sun for a long time in summer, which may easily cause blisters and other phenomena in the packaging bags, which will affect the packaging quality

Abstract

The invention discloses a sun-resistant packaging bag material, which is prepared from the following raw materials in parts by weight: 3-4 parts of isopropyl alcohol, 1-2 parts of sodium carboxymethylcellulose, 0.4-1 part of an ultraviolet light absorbing agent, 110-120 parts of polypropylene, 0.1-0.2 part of benzotriazole, 5-7 parts of dibutyl maleate, 3-4 parts of diphenyl silanediol, 1-2 partsof glycyrrhizic acid, 0.6-1 part of N-isopropyl-N'-phenyl-p-phenylenediamine, 1-2 parts of barium naphthenate, 2-4 parts of bisphenol A phosphite and 10-14 parts of diatomaceous earth. The ultraviolet light absorbing agent and the benzotriazole are added into the sun-resistant packaging bag material, so that the sun-resistant effect of the finished product material can be effectively improved; the diatomaceous earth is dispersed by using a sodium carboxymethyl cellulose aqueous solution, so that the dispersion uniformity of filler in the finished product material is effectively improved; therefore, packaging bags prepared from the sun-resistant packaging bag material has better mechanical properties, and the higher flatness stability of the finished products is guaranteed.
